Novel function of a putative MOC1 ortholog associated with spikelet number per spike in common wheat
Axillary meristems play an important role in determining final plant architecture and floral structures. Tomato Ls, Arabidopsis LAS and rice MOC1 are orthologous genes regulating axillary meristem initiation and outgrowth. Their functions are generally conserved but the functional specificities are divergent among species. Obvious differences between rice panicles and wheat spikes suggest the d...
متن کاملA Combined Association Mapping and Linkage Analysis of Kernel Number Per Spike in Common Wheat (Triticum aestivum L.)
Kernel number per spike (KNPS) in wheat is a key factor that limits yield improvement. In this study, we genotyped a set of 264 cultivars, and a RIL population derived from the cross Yangmai 13/C615 using the 90 K wheat iSelect SNP array. We detected 62 significantly associated signals for KNPS at 47 single nucleotide polymorphism (SNP) loci through genome-wide association analysis of data obta...
متن کاملThe nature of floral signals in Arabidopsis. I. Photosynthesis and a far-red photoresponse independently regulate flowering by increasing expression of FLOWERING LOCUS T (FT)
Arabidopsis flowers in long day (LD) in response to signals transported from the photoinduced leaf to the shoot apex. These LD signals may include protein of the gene FLOWERING LOCUS T (FT) while in short day (SD) with its slower flowering, signalling may involve sucrose and gibberellin. Here, it is shown that after 5 weeks growth in SD, a single LD up-regulated leaf blade expression of FT and ...
متن کاملEstimating Per-Locus Mutation Rates
Relative per-locus mutation rates for Y-DNA microsatellites, and also for mitochondrial DNA singlenucleotide polymorphisms, can be estimated directly from diverse collections of haplotypes without segregating population components. The calibrated average mutation rates for the FTDNA panels of 12, 25, and 37 loci are 0.00187±0.00028, 0.00278±0.00042, and 0.00492±0.00074, respectively, from a col...
متن کاملOverexpression of Arabidopsis FLOWERING LOCUS T (FT) gene improves floral development in cassava (Manihot esculenta, Crantz)
Cassava is a tropical storage-root crop that serves as a worldwide source of staple food for over 800 million people. Flowering is one of the most important breeding challenges in cassava because in most lines flowering is late and non-synchronized, and flower production is sparse. The FLOWERING LOCUS T (FT) gene is pivotal for floral induction in all examined angiosperms. The objective of the ...
